Abstract
An apparatus and a method for speech recognition are provided, by which, whereby the speech is optionally input via a microphone ( 14 ) close to the speaker or a microphone ( 20 ) remote from the speaker. A correction unit ( 15 ) is connected into the transmission channel ( 12 ) with microphone ( 14 ) close to the speaker, the correction unit modifying the electrical speech signal in such a way that it contains room transmission characteristics.
